WebAssembly could solve AI agents’ most dangerous security gap

Dan Phillips argued at Wasm I/O that WebAssembly can isolate untrusted AI-generated code to reduce security risks.

He said traditional sandboxes like containers or microVMs share a kernel, add overhead, and can be inefficient.

Phillips highlighted Wasm’s small module size, fast startup, and Boxer’s ability to run Dockerfiles as Wasm without rewrites.

He said isomorphic computing would let the same agent code run across browsers, phones, cloud, and home servers.
